WEATHER COVERING MATERIAL Y Filed Mar-ch 10, 1943 Patented Jan. 16, 1945UNITED s'mcr-lezfsy PATENT OFFICE Donald 'ru110h,Jr.,n0uy oak, nel. lApplication Maren 1o, 194s, serial nagaan 6 claims. (o1. 10s-s) Thisinvention relates to composition or rigid Weather surfacing elements,and more rparticularly to roong and siding strips molded from a plasticmass of cement-asbestos or other suitable .composition which sets intohardened or indurated character. verse or vertical ribs or elevations onthe weather exposed surface and so disposed to simulateindividualshingles and prevent them from curling.

Generally described, the invention comprises roofing or siding stripswhich are of substantial lengths provided with transverse orverticalribs or elevations to reenforce the 'strips and prevent themfrom curling, particularly at the weather exposed butt edge, ends andcorners. Moreover, the

The strips are provided with transf numeral l shows a surface, such as asheathing i of a Wall or roof structure, which is covered withtransverse or vertical ribs or yelevationscan be arranged to give adecorative design, such as being spaced apart to set off the Weatherexposed surface of the strips in the form of simulated individualshingles or. other decorative designs.` The ribs or elevations may be ofgradually diminishlapped courses 2 of strips 3 laid in end to endrelation. The strips may be made of any composition usually employed inmaking tile or other composition shingles or sidingstrips. One preferredcomposition ywhich* is especially suitable for the invention is acomposition composed of cement and asbestos. The mixed mass is molded byconventional vmethods in suitable molds, between forming `rolls or inhydraulic presses,

The strips are oi'indefinite length and width,

but lare advantageously formed in strips equal to about the width ofthree or four individual shingles. Usually theyy are about thirty-sixinches long.

'The' strips .are provided with ribs or elevations 4 transverselydisposed at'spaced intervals along the length of the strips; The ribs orelevations ing thickness from the weather exposed butt edges of thestrips to the upper or lap marginal edge. They preferably do not extendinto the upper or lap marginal edge over which the bottom of ai 'I'heopposite ends of the strips or shingles may 4 be rabbeted :in order thatthe strips when laid end to end in courses on the rooiing structureWillintert.

For a better understanding of the invention, reference is made to theaccompanying drawing,

Fig. 2 is a partial vertical section on line 2 2 of Fig. l;

Fig. 4 is a partial section on line 4--4 of and Fig. 5 is a perspectiveview of a weather surfacing element sho-wing a modification of thenailing means.

Referring specically yto the drawing, in which.

tinuous and gradually sloped away at 5 to merge The ribs do not "onlyfor the width ofthe portion which is to be exposed to the weather. Theyare shown in the present embodimentfof equal elevation throughout theirwidths, but they may gradually diminish in thickness from the butt edge'l to the lap portion 8 on the upper face side of the strip. The lapportion is preferably two or more inches wide.

The marginal elevations or ribs 4a and 4b at the end of the strips `areone half as wide as the intervening ribs or elevations 4, and rib 4a isset back from the edge of the strip while rib 4b projects over theopposite edge of the strip equal to the set back distance of rib 4a.Accordingly the ends of the adjacent strips will intert and form rabbetjoints 9 when laid.

Recesses l0 for nails are provided in the upper margins of the stripsalong the lap which is to be covered by the bottom margins of strips inan overlying course. The recesses for the nails are preferably in medialvertical alignment with the elevations or ribs, particularly the e'ndribs or between the edges of the 'strips and the areas in the lap whichare in alignment with the ribs or elel vations. The nails thus cooperatewith the ribs or elevations and in these end areas hold down the-ends ofthe shingles so that they may be vprevented from curling by reason ofthe ribs or elevations.

elevations and the nailing may be placed there. The ribs or elevationsextenuate the thickness of the lstrips and simulate a more massiveappearance.

1n Fig. 5 the nailing means are not in medial vertical alignment withthe channels or elevated portions or between the edges and the areas ofthe lap po-rtion which is in alignment, but are closely adjacent theretoin order that the nailing means may be in position to. cause.. the ribsto prevent any curling of the bottom cornersA of the strips. The outsideor extreme end nailing means should be in vertical alignment with themain portion of the ribs or where the ribs merge into the body of thestrips. i

Having described the invention and certain embodiments to exemplify it,I claim:

1. A rigid weather covering unit rpxriposed of indurated hydrauliccement composition materia] and having the weather exposed surfacedividedl into a plurality of individual shingle simulating areas, anintegral vertically disposed por-tionof greater thickness on eachmarginal end. 0f the unit to reenforce same and prevent the exposedcorners from curling, and nailing .portions provided closely adjacenteach of the vertical portions o'f greater thickness to cause themarginal ends of increased thickness to prevent the exposed corners ofthe unit from curling.

2. A rigid weather covering unit composed oi indurated hydraulic cementcomposition material and having the weather exposed surface divided intoa plurality of individual shingle simulating areas, an integralvertically disposed portion of greater thickness on each marginal endand be*- tween adjacent individual shingle simulating areas of the unitto reenforce same and prevent the exposed corners from curling; andvnailing portions provided closelyA adjacent each of the verticalportions ofV greater thickness to cause the marginal ends of increasedthicknessto prevent the exposed corners. of the unit from curling.`

3. A rigid weather covering unit composed of v indurated hydrauliccement composition material and having the weather exposed surfacebetween integral vertically disposed marginal portions of greaterthicknessthan thel'ortions therebetween toy prevent. the. exposedcarriersrof the; unit. from curling, and a nailing portion providedclosely adjacent each of the Vertical portions of greater thickness tocause the marginal ends. of increased thickness to prevent the exposedcorners of the unit from curling. 1

4. A rigid weather covering unit composed of indurated hydraulic cementcomposition material and having the weather exposed surface betweenintegral vertically exposed marginal portions of greater thickness thanthe portions therebetween, ther marginal portion of increasedthicknessbeing slightly spaced back from one end of the unit i and themarginal portion of increased thickness being slightly projected beyondthe opposite end ,andcomplemental with the opposite end, and a nailingportion provided closely adjacent each of *the-vertical Vportions ofgreater thickness to cause the, marginal ends of increased thickness toprevent the exposed corners of the unit from curling.

5. A rigid weather protecting covering comprising lapped coursescomposed of covering units composed of indurated hydraulic cementcomposition material andhaving the weather exposed surface betweenintegral vertically disposed marginal end portions of greater thicknessthan the portions therebetween to prevent curling of the weather exposedcorners of the units, and nailing means provided closely adjacent eachof the vertical thickened end portions and covered by the overlyingunits, the closely adjacent nailing means preventing the exposed cornersof the unit from curling.

6.l A rigid weather protecting covering comprising lapped coursescomposed of covering units composed of indurated hydraulic cementcomposition and, having the weather exposed surface between integralvertically disposed marginal end portions of greater thickness than theportions therebetween, said vertically disposed marginalA end portionsterminating short of the upper edge to provide a lap., and nailing meansprovided in the lap closely adjacent the ends of the units and coveredby overlying units Whose butt edges are aligned with the ends of thethickened portionsfthe closely adjacent nailing means preventing theexposed corners of the unit from curling.
